When your having a piss and it becomes surprisingly out of control, spraying everywhere and maybe even pushing u back from all the force of the piss coming out of the cock. imagine a hose pipe left on the ground with water coming out of it at full blast. If that happens when u piss, ur havin a wazilinki.

Dan: Is Wainer in the toilet?
(from within toilet): UHHHHHHHHHHHHHHHH!
Nick: Yup, that's him
Dan: sounds like he's havin a good wazilinki in there.
